Abstract: A system for raising and lowering equipment and including a fixed support arm for attachment to an elevated support structure, a movable carriage for carrying the equipment, a cable extending between the fixed support arm and the movable carriage, and a winch for spooling and unspooling the cable to raise and lower the movable carriage relative to the fixed support arm. A locking mechanism secures the carriage in its raised position, and alignment guides position the carriage to make electrical connections as the carriage is engaged onto the support arm.

Abstract: A reconfigurable connectorization panel assembly for a circuit board housing rack or chassis, particularly suitable for use in cable television (CATV) headend equipment. Each circuit module for use in the rack has an associated rear panel assembly or "connectorization panel" that bolts onto the rear side of a chassis which supports the rack and a backplane. The connectorization panels extend plug-action connectors through openings in the rear panel of the chassis and in the backplane, and mate with corresponding connectors on the circuit modules. On the rear side, the connectorization panels provide appropriate drop side connectors required for input/output signal cabling. The connectorization panel adapts a particular slot in the chassis for a particular type of input/out cabling and connectors. The slot can be reconfigured for a different type of circuit module by affixing a different type of connectorization panel.

Abstract: A fiber routing and retention assembly for routing and mounting at least two fibers having a terminal end within an electronic enclosure. The assembly includes a fiber routing track, a fiber tray, and a pivot arrangement. The fiber routing track includes horizontal and vertical legs, each having a guide channel for guiding and retaining the fibers. The fiber routing track also includes attachment structure, preferably projections, for attaching the fiber routing track to the electronic enclosure. The fiber tray retains and routes the fibers therein, including the terminal ends of the fibers, and has a raceway including inner and outer walls for routing the fibers therebetween. The pivot arrangement is coupled to the fiber routing track and the fiber tray permitting the rotational movement of the fiber tray with respect to the track between a stowed position and an access position.
